You'v done real good her. Such a nice athmosphere and beautiful lighting. # 2 works best for me, as the first one scares me a bit, with them blue eyes. A bit too much CienceFiction'ish for my taste anyway....

And now your two latest with your son in the usual Polarbear-fur position (most of my generation baby-pics were done with the motive lying on a polar-bear hide...), are very good also. Such great facial expressions and very good and important eye-contact!
